Short answer Type questions
1 What steps are needed to prevent soil erosion in hilly areas?
Answer – To prevent soil erosion in hilly areas, the following steps are needed-
(a) Forest plantation or plantation of trees in large quantity can be stopped in the process of erosion. Planting trees on barren land and hill slopes proves to be more beneficial. Wind erosion can also be prevented in this manner.
(b) Gully erosion can be prevented by making terraced fields on the mountain pulses. Due to this, proper use of water flow can be done.
(c) By making dams on the mountain slopes, water flow can be properly used for agriculture. Earthen check dams can stop the spread of gullies (or deep ditches formed by water).
(d) For land conservation, it is necessary to recognize the spread of soil erosion and adopt appropriate methods to stop it.
(e) Another means of preventing soil erosion is that grazing by animals, especially in hilly areas, should not exceed the limit.
2 Describe the land use pattern in India. What is the reason for the absence of a significant increase in the area under forest from the year 1960-61?
Abstract: Land is an important natural resource because most human needs are met directly or indirectly from the land. Hence human prosperity is possible only through the proper use of land. The present form of land use in India is the result of the geomorphological structure, climate, soil, and human activities. The total geographical area of India is 32.8 lakh sq km! • Of which only 93% of land use data is available. The details are as follows-:
(a) Agriculture is done on 51% of the total area of India, if fallow land is also included in it, it increases to about 5496
(b) The share of land under forests is about 22% which is much less than the 33% required for ecological balance.
(c) There is 4% of pasture land in our country. Although India has the largest number of animals in the world. Therefore, the pasture land is also less in proportion to the number of animals.
(d) About 6.2% of the land is barren land which is unfit for agriculture. (e) In addition, the rest of the land is used for non-agricultural purposes such as settlements, cities, rivers, ponds, roads, railways, temples, mosques, etc. The following are the reasons for the non-significant increase in the area under forests since the years 1960-61-
(a) Due to rapid population growth in India, the land is being used to support the additional population.
(b) Forests have been cut down indiscriminately and relatively fewer new trees have been planted.
(c) Due to the expansion of industries, mining, development of multipurpose river valley projects, forests have been degraded.
(d) Due to the expansion of cities, settlements, roads, and railways, there has been an increase in the forest area.
3 How did technological and economic development lead to the overuse of resources?
Ans- (a) More use of resources is related to technological and economic development. Due to the development of technology, the exploitation of resources became possible on a large scale, and more and more resources were required for economic development.
(b) Availability of resources in itself cannot lead to development unless technology or skill is developed to make use of it. As technology progressed, the resources were exploited on a large scale.
(c) The more resources were exploited, the more the economic development progressed.
(d) The exploitation of resources took place on a large scale during the colonial period as the imperialist countries exploited the resources through their high technology. This strengthened the economic condition of the imperialist countries. Even though the colonies did not get their benefit.
4. What is land degradation or land degradation? Explain any four causes of land degradation.Or, What is meant by soil erosion?
Answer- Due to natural and man-made reasons, the continuous decrease in soil fertility or fertility is known as land degradation or land degradation.
The following are the causes of land degradation-
(a) Land erosion- Land erosion is the main factor of land degradation. Wind, water, glaciers, etc. destroy the upper layer of the land, which is known as land erosion. This reduces the fertility of the soil.
(b) Land pollution – Due to the polluted water coming out of the industries and the garbage lying in the same place for a long time, the essential elements of the land get depleted and the land does not remain fit for use. This is known as land pollution.
(c) Defective farming method – The fertility of the soil also decreases by the production of many crops on the same land.
(d) Animal grazing and deforestation- Due to overgrazing by animals and indiscriminate cutting of forests, land is degraded, that is, its fertile power decreases.
(e) Industry Business- Grinding of limestone for the cement industry, breaking of rocks by crushers and porcelain-making industries, a large amount of dust gets deposited in the fields, as a result of which the fertility of the soil decreases. Is.
5. Give some measures to prevent soil erosion or soil erosion.
Answer – Measures to prevent soil erosion or soil erosion-
(a) The amount of soil erosion can be reduced by doing terrace farming in hilly areas.
(b) Land erosion can be prevented by planting trees around the desert area.
(c) Land erosion can be controlled by planting small plants and grass etc. in areas with high rainfall.
(d) Soil erosion can also be controlled by alternating cultivation of different crops on the same land.
(e) By using screwer machines in industrial units, dust does not accumulate in the fields, and soil erosion is reduced.
(f) Soil erosion can be controlled by using a separator filter to take out the polluted water coming out of the industries.
6 What do you understand by soil conservation? Why is soil conservation necessary?
Answer – Preventing soil erosion and maintaining its original properties is called soil conservation.
India is an agricultural country. Soil has a special contribution in making it agricultural. Indian soil is very fertile, deep, and diverse, due to which not only different types of crops are grown in India, but it can become the world’s leading exporting country in the production and export of many crops. All this is possible when we keep protecting our soil equally.
7 What is the importance of natural wealth or resources?
Answer – Importance of natural wealth or resources – (a) They are the main means of our agricultural activities.
(b) They provide raw materials for our industries.
(c) All our business activities are directly or indirectly dependent on them.
(d) They maintain natural beauty and play an important role in maintaining balance with the different organisms of the biosphere.
8 What are the different bases of classification of resources?
Answer- Classification of resources can be done on the following basis-
(a) On the basis of origin biotic and abiotic
(b) renewable and non-renewable on the basis of maturity
(c) individual, community, national, and global on the basis of ownership
(d) On the basis of the level of development.
Discuss the need of the conservation of resources.
Answer – There has been a continuous use of resources due to the growth of population and economic development. If this rate of consumption continues, then one-day economic development will stop and the existence of human civilization will be in danger. Therefore, the conservation of resources has become essential. The need for the conservation of resources is due to the following reasons-
(a) Due to human habitation, land has become scarce in the settled regions. Houses are being built on land used for agriculture. Therefore, it has become necessary that the available land should be used in a planned manner.
(b) Due to the continuous use of underground water, the water level has gone down, due to which agriculture is being badly affected. Therefore, the conservation of groundwater has become necessary.
(c) The environment is getting polluted due to the continuous harvesting of forests, if attention is not paid to the conservation of forests, then the pollution will increase so much that human life will be in danger.
(d) It would be impossible to set up and run factories without mineral resources and power resources. Therefore, the use of mineral resources has to be done very judiciously.
10 What are the main types of resources on the basis of ownership?
Answer – On the basis of ownership, resources are divided into the following parts-
(a) Personal resources- land, houses, gardens, etc. under personal ownership.
(b) Community-owned resources – including village land (pasture land, cremation ground, pond, etc.), city public park, picnic spot, playground, etc.
(c) National resources – roads, canals coming within the national boundaries,
Two objectives of conservation of resources-
(a) Its first objective is that the present generation should get all these resources like railway lines, all minerals, water resources, forests, government land, and government buildings, etc.
(b) International resources – open ocean resources beyond a distance of 200 km authorized by international organizations.
How many types of resources are there on the basis of the level of development?
Answer – On the basis of the level of development, the following are the types of resources- (a) potential resources, (b) developed resources.
Potential resources are those resources that are present in any state but are not consumed, such as solar energy in Rajasthan and wind power in Gujarat, but they have not been properly developed yet. Those resources which have been evaluated and are being used are called developed resources.
12 What is meant by conservation of resources? State two objectives of conservation of resources.
Answer – The judicious and planned use of natural resources is called the conservation of resources.
(b) Its second main objective is that we should keep in mind the interests of our generation as well as fulfill the needs and aspirations of future generations.
13 When and why did the Earth Summit of Rio de Janeiro take place?
Answer- The Earth Conference of Rio de Janeiro was held in the Brazilian city of Rio de Janeiro in 1992 to think about the 21st century for sustainable development of countries around the world. In this, it was decided how to deal with environmental damage, poverty, and diseases through cooperation according to common interests, mutual needs, and shared responsibilities.
14 What is resource planning? Describe the steps of resource planning in India. Or, What is meant by resource planning? resource planningMention the two levels.
Ans- The planned and judicious use of resources is known as resource planning. Planning of resources is necessary for the following two reasons-
(a) the amount of resources is limited,
(b) Distribution of resources is unequal.
Resource planning is a complex process, which consists of the following steps:
(a) Identifying resources in different regions of the country and making their table. In this work, field surveys, map making, and qualitative and quantitative estimation and measurement of resources are done.
(b) To create appropriate technology, skill, and institutional planning framework for implementing resource development plans.
(c) To coordinate the resource development plans and the national development plan.
15 Write the main characteristics of alluvial soil?
Answer – Alluvial soils are very fertile. Most of the alluvial soils are rich in potash, phosphorus, and lime, which makes them suitable for the cultivation of sugarcane, rice, wheat, and other cereals and pulses. Due to high fertility, intensive agriculture is done in areas with alluvial soil and population density is also high here. The soils of dry areas are more alkaline. By proper treatment and irrigation of these soils, their yield can be increased.

3. Give a brief account of the major types of soils found in India. OR Write in brief the distribution of alluvial and black soils in India.
Answer – In a vast country like India, many types of soils are found such as laterite soil, red soil, alluvial soil etc.
Alluvial soil- Alluvial soil is found in a large area of the country. It is mainly found in northern plains, coastal plains and especially in the Chhattisgarh basin. This soil is very fertile and is very useful for agriculture. This soil is formed from the materials (i.e. sand, silt, clay, etc.) brought by the continuously flowing rivers. Such soil is mostly found in the valleys of rivers like Sutlej, Ganga Brahmaputra (which flows in north-eastern India), Mahanadi, Godavari, Krishna, and Kaveri (which flows in Tamil Nadu). The alluvial soil of the northern plains is of two types – Bangar and Khadar.
Black soil – It is made from the spread of lava, hence its color is black. Black soil is found in Maharashtra, Madhya Pradesh, Kathiawar (Gujarat), Karnataka, Andhra Pradesh, and Tamil Nadu. Black soil is also called regur soil. Somewhere this soil is deep and somewhere less deep. This soil is very fertile and especially useful for cotton cultivation. The production of pulses etc. is best in this soil.
Red and yellow soil- Iron content is more in this soil, hence its color is red. This soil is found in Tamil Nadu, Karnataka, Andhra Pradesh, Chhattisgarh, Odisha, and Jharkhand. Its development is due to the effect of water vapor changes from the rocks found on the plateaus. This soil is fertile. and is suitable for agriculture. Red soil is found in the following parts-
Laterite Soil- Laterite soil is mainly found in the hills of Deccan, Karnataka, Kerala, Orissa, Assam, and some parts of Meghalaya. This type of soil is formed as a result of an intense leaching process due to excessive rainfall. It looks like a red layer lying on the surface of the soil and due to not being suitable for agriculture, it has been considered more suitable for afforestation. Forests of eucalyptus, cashew, and many other trees have been planted in the areas of this soil.
Mountain and forest soil- These types of soils are mostly found in mountainous areas. Such soils are formed by the accumulation of vegetative and organic parts. These differ from one place to another. spread of these types of soils
Can be seen in hilly states especially Jammu and Kashmir, Himachal Pradesh, Uttaranchal, the eastern ranges of Arunachal Pradesh, and Meghalaya. Desert soil – Such soils are found in arid and semi-arid regions. Such soil has more sand particles, so it is not as fertile. But with the availability of irrigation facilities, these soils can also be used, as is being done in the Ganganagar region of Rajasthan. Desert soils are found in a wide area of Rajasthan, Punjab, and Haryana.
